A pressure mounting assembly which is particularly suitable for mounting high power electronic components such as thyristors is provided with an indicator to indicate when a predetermined mounting pressure has been reached. The pressure mounting assembly consists of two pressure rings 3 and 4 which initially are forced by disc washers 5 against internal abutments 6 and 7 formed in the wall of a cylindrical shell 1. When a predetermined mounting pressure is achieved the disc washers 5 are compressed due to loads on collars 9, 10 sufficiently to free the rings 3 and 4 from the abutments band 7 so that the shell 1 is free to rotate under the action of a torsion spring 5 thus providing an indication that the predetermined load has been reached. <IMAGE> |
